In today's society, the automobile as an indispensable means of transport, on the progress of human society had a huge role, but at the same time, environmental pollution, energy shortages brought about by the traditional internal combustion engine vehicles and more problems. As pure electric vehicles with internal combustion engine vehicles incomparable advantages in energy conservation and environmental protection, it's put into operation is conducive to reduce human dependence on oil resources, can vigorously alleviate the global energy crisis and environmental problems, a pure electric vehicle research and development has become a national government and auto industry hot spots, electric vehicles will become the 21st century green transport. In this paper, relying on the light pure electric passenger through simulation technology, made more in-depth understanding of the performance characteristics of the light pure electric buses as well as design rules, validation reasonable match the the light pure electric passenger vehicle program, which can shorten design cycle, reducing development costs and improve the performance of electric vehicles. Test evaluation, you can build an evaluation platform for electric vehicles, especially the light pure electric bus test. First of all, the course of development of pure electric vehicles, development status at home and abroad, the basic structure and features, advantages and shortcomings are discussed, and discusses the need for a pure electric vehicle development. And pure electric vehicle power system modeling and simulation and test evaluation of the status quo, the light of pure electric bus power system modeling and simulation, and testing and evaluation methods. Second, MATLAB / Simulink environment, simulation software ADVISOR platform to establish a model of the lightweight pure electric passenger vehicle, wheel / shaft model, the main gear box model, transmission model, the model of the motor and drive controller and power battery model, and for the software only on the front-wheel drive car performance simulation of limitations, changes to the rear-wheel-drive model, the completion of the second development. With the established model of the the created power system simulation analysis, simulation results demonstrate the parameters match the reasonableness of the rear-wheel-drive vehicle power system modeling accuracy and power system components. Finally, the paper describes a lightweight pure electric passenger car-like vehicles on the road and on the chassis dynamometer tests and taxiing test data processing method, set up the of light pure electric vehicle testing and evaluation system. Through vehicle road test and on the chassis dynamometer test to further verify the reasonableness of the light of pure electric passenger vehicle matching program. And contrast the two chassis dynamometer the resistance setting method, and provide a reference for future light pure electric buses.
